About

What is rhino?

Rhino is Picovoice's on-device Speech-to-Intent engine, leveraging deep learning to infer user intent directly from spoken commands in real-time. Designed for efficiency and compactness, it's particularly well-suited for embedded systems and IoT devices, operating entirely offline. Developers can train custom contexts using the Picovoice Console, defining specific voice commands, intents, and slots to capture details like 'turn off the lights in the $location:lightLocation'. Rhino supports multiple languages and offers SDKs for various platforms including Python, .NET, Java, Flutter, React Native, Android, iOS, Web, and C, making it highly versatile for integrating voice interfaces into diverse applications.

Best used for

Ideal for developers who need to embed real-time, offline voice command recognition into IoT devices, mobile apps, and web applications. Especially valuable for creating custom voice interfaces for specific domains, such as smart home control or industrial automation, where privacy and low latency are critical.

FAQs

What kind of voice commands can Rhino process?

Rhino is designed for specific, domain-limited voice interactions. It infers intent and extracts specific details (slots) from commands like "Turn off the lights in the office" or "Set the kitchen lights to blue," making it suitable for applications with a defined set of actions.

Can I create my own custom voice contexts with Rhino?

Yes, developers can create custom contexts using the Picovoice Console. This allows you to define your own expressions, intents, and slots, tailoring the voice recognition to the specific needs and vocabulary of your application or device.

What platforms and programming languages does Rhino support?

Rhino is highly cross-platform, supporting Arm Cortex-M, STM32, Arduino, Raspberry Pi, Android, iOS, Chrome, Safari, Firefox, Edge, Linux, macOS, and Windows. It offers SDKs for Python, .NET, Java, Flutter, React Native, Android, iOS, Web (JavaScript), and C.
